The rear lighting system on the DeLorean is presented via two identical lighting elements mirrored in placement to each other. The units mount left and right, respectively, on the rear fascia assembly. The light bulb elements are mounted into sockets integrated into the boards.
The boards are identical, allowing for the testing of independent system functions. The five bulbs result in four distinct functions throughout vehicle operation. From the middle of the assembly going towards the side of the vehicle are: back up, brake light, taillight, brake light, and turn signal indication.
When faced with servicing the bulbs, there are ten to be replaced.
The eight outer and secondary inboard bulbs are 21 W single contact.
